The ongoing experience of panic disorder was assessed in 20 female
subjects, to determine psychological precursors to panic attacks. Measures
of anxiety, threat, control, prediction of panic, and symptoms were
assessed at hourly intervals during waking hours for one week. Measures
were taken using a portable computerised diary which prompted for and
stored responses. Patients' ratings of the prediction of panic attacks were
the only significant precursors to panic attacks. This supports recent
research that expectancy is important in panic onset. The data also
suggested that anxiety levels follow a circadian pattern.
